DRAFT APPLIANCE.

SpecificationofLetter's Patent.

Application filed December 7, 1912.

Patented Nov. 18, 1913.

Serial No. 735,570.

To all whom it may concern:

Be it known that I, ANDRO KRIvoNYAK, a subject of the Emperor of Austria-Hungary, residing at Saltsburg, in the county of Indiana and State of Pennsylvania, have mvented certain new and useful Improvements in Draft Appliances, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a draft appliance v for the cars of industrial railways, and more particularly to a draft appliance that can be advantageously used in connection wlth a pit car. 4

The primary object of my invention is to furnish an end of a car with an appliance that will reduce the stresses and strains upon the coupling to a minimum and thereby prevent coupling pins and links from being broken when subjected to strain.

A further object of this invention is to provide a draft appliance consisting of comparatively few parts that are easy to install, inexpensive to manufacture, durable and highly efficient for the purposes for which they are intended.

With the above and other objects in view the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawing, wherein Figure 1 is a longitudinal sectional view of the ends of cars coupled in connection with the draft appliance, Fig. 2 is a side elevation of a draft bar, partly broken away and partly in section, Fig. 3 is a plan of the same, and Fig. i is a side elevation of a modified form of draft bolt.

Further describing my invention in detail with reference to the accompanying drawing, wherein like numerals denote corresponding parts throughout: 1 denotes a portion of a car having an end wall or gate 2 and a false bottom 3.

The reference character 4 denotes a flat draft bar located beneath the false bottom 3 and longitudinally of said car. The bar 4, at one end thereof, is bent upon itself and apertured, as at 5 to provide a coupling member. Said bar is furthermore bent as at 6 to engage the end of a car and said bar is held in engagement with said car by a bolt 7, a nut 8 or other fastening means. The opposite end of the draft bar is bent to form a yoke 9 and the end 10 of said yoke extends under the car and is connected thereto by a bolt 11 and a nut 12.

The reference character 13 denotes a draft 6O bolt arranged longitudinally of the yoke 9 and one end of said bolt terminates in an eye 14 and the opposite end thereof is-screw threaded, as at 15 to receive nuts 16 and 17. These nuts limit the movement of the draft bolt in the yoke 9.

The reference character 18 denotes a coiled spi ing encircling the draft bolt within the yore.

The reference character 19 denotes links connected to the eye 14 and said links have an open link 20 that is connected to the coupling member 5 by a pin 21. The pin 21 is connected by a chain or flexible connection 22 to the end wall Or gate of the car.

The spring 18 compensates for any stresses or strains between the coupled cars, thereby preventing the coupling pin 21 and the links 19 and 20 from. being broken.

In Fig. 4 there is illustrated an angularly 80 disposed draft bolt 13 and the arrangement of this bolt maintains a straight connection between two cars and places the eye 14 in the same plane as the coupling member of an adjoining car.

One embodiment of the invention has been illustrated, but it is to be understood that the structural elements are susceptible to such changes as fall within the scope of the appended claim.

What I claim is A draft appliance comprising a longitudi nally extending bar having one end bent to provide an inverted yoke having its top disposed above the plane of the bar, the outer arm of said yoke, being of greater length than the inner arm, and depending below the plane of the bar and having its lower end bent inwardly to engage the under face of end constructed to receive means for couthe end of a car, said arms provided with pling a car thereto. 10

alining openings above the plane of the bar, In testimony whereof I aflix my signature a spring controlled draft bolt extending in the presence of two witnesses.

through said openings and having its outer ANDRO KRIVONYAK. end provided With an eye and its inner end Witnesses:

with a stop to limit the outward movement MAX H. SRoLovrrz,

of the bolt, and said bar having its other I KATHERINE ERRETT.
